Warning lights on
panelWhat it means What to do
amberINJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to
MAR-ON the warning light switches on, but it should
switch off as soon as the engine is started. The operation
of

If the warning light remains on or switches on whilst
driving, it means that the injection system is not working
properly. The warning light on constantly signals a
malfunction in the supply/ignition system which could
cause high exhaust emissions, a possible loss of
performance, poor driveability and high consumption.
On some versions, the display shows the dedicated
message. The warning light goes out after the fault
disappears: the indication is stored in the system.Under these conditions, you may continue
travelling at a moderate speed without
demanding excessive effort from the
engine. Prolonged use of the car with the
warning light on constantly may cause
damage.
Contact an Alfa Romeo Dealership as
soon as possible.
Petrol engines only
If the warning light flashes, it means that the catalytic
converter may be damaged.In this case, release the accelerator pedal
to lower the speed of the engine until the
warning light stops flashing. Continue the
journey at moderate speed, trying to avoid
driving conditions that may cause further
flashing and contact an Alfa Romeo
Dealership as soon as possible.

Warning lights on
panelWhat it means What to do
amberDPF CLEANING (particulate trap) in progress
(diesel versions with DPF only)
When the key is turned to MAR-ON, the warning
light switches on but it should switch off after a
few seconds. The warning light switches on
constantly to indicate that the DPF system needs
to eliminate the trapped pollutants (particulate)
through the regeneration process.
The warning light does not come on during every
DPF regeneration, but only when driving
conditions require that the driver is notified. To
turn off the warning light, keep the car in motion
until the regeneration process is over.
On average, the process lasts 15 minutes.
Optimal conditions for completing the process are
achieved by travelling at 60 km/h with engine
speed above 2000 rpm.
When this warning light switches on, it does not
indicate a car failure and thus it should not be
taken to a workshop. On some versions, together
with the warning light switching on, the display
shows a dedicated message.

116
KNOWING THE INSTRUMENT PANEL
WARNING
69) Always drive at a speed appropriate to the traffic conditions, the weather and traffic regulations. The engine can be
stopped even if the DPF warning light is on: however, repeated interruptions of the regeneration process could cause
premature deterioration of the engine oil. For this reason, always wait until the warning light switches off before
stopping the engine as described above. It is not advisable to complete DPF regeneration with the car stationary.
